iPhone Finger Prosthesis

The success of iphone is a result of a carefully designed easy-to-use user interface. Using a multitouch interface you can take control of your application by making more free gestures, not repeating the unanimous button pressing. The intelligent sensors equipped with multitouch interfaces are likely to overthrow the only option of the more than a hundred years of keyboard-display combo.

Our aim

The finger prosthesis project is a playful reflection for the potential problems of iphone interface, or variations to this interface to be more effective, or less effective. On the multitouch interfaces, the focus is on the human finger and the human hand in a more lively way.

Your finger gestures are no longer reduced for only a rigid stroke of the button, but a more real human finger and hand gestures with its entire anatomy. This interface is, moreover, is not a closed form, since the interface is a combination of the hardware and the software side. Although some of the typical multitouch gestures are already starting to become a standard (zoom, rotation), there are in principle an infinite number of variations of the gestures. The software side is therefore able to interpret 2, 3, 4, or 5 finger gestures and we can define function for these gestures.

How does it work

It is possible that someone’s finger is too thick or too thin in order to deal effectively with multitouch interface. The finger prosthesis provides a solution for this difficulty of which it ables the user to achieve the most suitable finger size to control the iPhone. With this help we can convert a too much thick or too much thin finger to the ideal size or we can even make a double finger of ine finger. So, the iphone will be better managed, or maybe less effectively managed, it is funny however to have an additional finger prosthesis along with our phone device.

Current state

The first time we make fingers of silicon interwoven with metal strings with a thickness of the ideal finger for iphone. We plan to provide finger prostheses in several sizes: for children, or in particular a thick-fingered users, as well as normal size fingered users for testing purposes.

Possible development of iphone applications will then be developed for the finger prosthesis. It is also an option to take these finger prostheses as fetish, to apply visual tuning on them by LEDs, electronics, or graphics. Then the finger prosthesis can also function as an ornamental mobile hanger during the time it is out of use, and what’s more, the "blue finger" will be able to communicate with the iphone.

The cultural tradition of the finger itself may be brought in connection with the project, concerning the role of finger on Michelangelo's fresco of Creation, or even E.T.’s lighting finger.
